Lady Gaga was in her bikini earlier this week to hang out at the beach in Mexico. There were some surf lessons in store for Gaga while she was on a vacation with friends, but the pop star's already back in NYC getting down to work again. The video for her latest single "You and I" came out Tuesday on Twitter, and she was at MTV yesterday doing press for the new tune. Lady Gaga was in their studios to officially launch the video on TV, and she spoke about the clip's metaphors and messages. She has more work coming with the network at the MTV VMAs. Gaga's prepping for a much-anticipated performance at the award show on Aug. 28, and she's rumored to even have the honor of opening the show. Also coming up for Lady Gaga will be a collaboration with Cher. The two icons are working on a song called "The Greatest Thing Ever," which will appear on Cher's upcoming 26th album.
